[ADMB Users] glmmADMB error message

[Lisa Denmead]

Hi,

Up until earlier today I have been using glmmADMB with no real issues, but
now every model I try and run comes up with the error below, even though I
have run it with this data before. I have been in contact with some other
students using this and they seem to be having the same problem, yet none of
us can figure out where we are going wrong. Any advice would be greatly
appreciated!
